Lazio coach Vladimir Petkovic admits they were left frustrated with defeat to Genoa.

Marco Borriello scored on a classic counter-attack, but was also given the chance to surge forward undisturbed because Giuseppe Biava pulled up with cramp.

"One can never be satisfied after a defeat, but we didn't do so badly as to deserve this result," Petkovic said of the 1-0 defeat.

"We had so many chances and conceded a goal after a slip, but this is football. We have to accept it and compliment our opponents for making the most of their opportunities.

"In the first half we lacked determination, while after the break we pinned Genoa back, but were not clinical enough.

"Hernanes showed again tonight that he is a complete midfielder who works to win the ball back, to create chances and go one-on-one. He is very important for our team."
